Poly (Lactic Acid) (PLA)/Recycled Styrene Butadiene Rubber (rSBR) Composites

Received: 01 March 2022;  Published: 11 April 2022;  doi: 10.21926/aeer.2202012

Abstract

Recycled styrene butadiene rubber (rSBR) from waste car tires was used as a filler in poly(lactic) acid (PLA) to modify its properties. The compounds were prepared via twin-screw extrusion and molded by injection with different rSBR contents (0 to 25% wt.). Additionally, recycled rubber [...]

Cyanobacterial Blooms and Their Implications in the Changing Environment

Received: 03 January 2022;  Published: 16 March 2022;  doi: 10.21926/aeer.2201011

Abstract

Cyanobacteria are the most ancient phytoplankton that first appeared at least 2.5 billion years ago and have a prolonged evolutionary history. They can form impenetrable and toxic blooms in aquatic ecosystems such as freshwater and marine environments. Cyanobacterial blooms produce cyanotoxins that [...]

A Case Study of How DHL Practices Carbon Management

Received: 10 January 2022;  Published: 10 March 2022;  doi: 10.21926/aeer.2201010

Abstract

Awareness of the challenges of sustainable development, and in particular the risks of climate change, is leading to inevitable restrictions on greenhouse gas emissions. Companies must now adopt a systematic approach to sustainable development. This issue is particularly important as true carbon ri [...]

Relationship between Thermal Variance and Hatchery Estimates of Fertility in a Multispecies Assemblage of Anadromous Salmonids in Response to Managed Flows

Received: 15 November 2021;  Published: 22 February 2022;  doi: 10.21926/aeer.2201009

Abstract

Our study sought to identify a regional explanation for declining fertility in stocks of co-occurring salmonids in the upper Trinity River, northern California, USA. We focused on evaluating the relationship between thermal variance in river water and hatchery-me [...]

NIR Spectroscopy and Aquaphotomics Approach to Identify Soil Characteristics as a Function of the Sampling Depth

Received: 24 December 2021;  Published: 15 February 2022;  doi: 10.21926/aeer.2201008

Abstract

Soil is a very complex medium made of minerals, organic matter, microorganisms, air, and water. Vibrational spectroscopy techniques are exceptionally well-suited to be used with portable and hand-held devices. In this study, NIR spectroscopy was applied using portable instrumentation and [...]

How Might Changing Climate Limit Cyanobacteria Growth in Shallow Prairie Lakes? An Empirical Space-For-Time Evaluation of the Potential Role of Increasing Sulfate

Received: 20 November 2021;  Published: 15 February 2022;  doi: 10.21926/aeer.2201007

Abstract

Cyanobacteria blooms alter aquatic ecosystems and occur frequently in shallow prairie lakes, which are predicted to increase in salinity as the regional climate becomes hotter and drier. However, flat landscapes that experience depression bottom salinity with high concentrations of sulfa [...]

Managing the Turf of An Urban Golf Course: Energy Consumption and Greenhouse Gas Emission

Received: 21 October 2021;  Published: 24 January 2022;  doi: 10.21926/aeer.2201003

Abstract

This study investigated energy consumption and greenhouse gas (GHG) emission across various playing surfaces (e.g., greens, tees, fairways, and roughs) in an urban parkland golf course. The turfs of golf courses require frequent maintenance to ensure high aesthetic and play quality. Main [...]
